Sennheiser EW-D AB (Q) 470 - 550 MHz

The Sennheiser EW-D AB is an antenna amplifier for the EW-D series from Sennheiser. This antenna amplifier boosts the antenna signal by 12 dB.

Setting new standards
Evolution Wireless Digital breaks current boundaries with a greater dynamic range than any other systems currently available. In everyday use, the system automatically searches for the best transmission frequency within seconds and allows for up to 90 additional channels thanks to a 56 MHz switching bandwidth. It is clear: the wireless system is in a class of its own.

Equidistant spacing – easier than it sounds
Evolution Wireless Digital features an equidistant frequency grid, which was previously only found in our flagship systems like Digital 6000 and Digital 9000. High-quality components with extraordinary linearity eliminate intermodulations between EW-D transmitters, allowing for frequency allocation every 600 kHz side by side. This simplifies coordination for both beginners and experienced users alike. Additionally, it contributes to the scalability of the system and the high channel limit.
